One wouldn't if they didn't check before leaving home. And when you got there, they posted a sign on how to register and it was quick, easy, and took less than two minutes. In this day and age, if you make the choice not to have a "smart phone", you know that it comes with certain limitations and that's a choice you made. Problem is, many want to blame others for their own choices and lack of due diligence. I believe it's why we have such a rise in "Karen's", entitled people who forget that the major tenent of freedom is personal responsibility for one's choices.
A few still choose to own no cell phone at all, but they know with that choice, they may have to walk if their car breaks down, and they take responsibility for that.
